The invention discloses a display device comprising a display panel, a backlight module and a rear light redirecting layer. The display panel has a bottom surface. The backlight module is provided on the bottom side of the display panel and has a light guide plate and a light source. The light guide plate has a first face opposite to the bottom surface and a second face parallel to the first face. The light guide plate further has an entrance surface located on a side of the light guide plate, and the light source is provided along the light entrance surface. The rear light redirecting layer is disposed at a position near the edge on the second face and includes a first region and a second region. A part of the light entering the light guide plate is emitted from the second side to the rear light redirecting layer and refracted through the first region and the second region to produce a different exit angle.
